The problem with the Situationists is that they have no political program. They refuse to describe how they would like the world to be, instead coming up with convoluted explanations for why doing so is unnecessary and counterproductive. The assertion is basically that capitalism is so terrible that once we get rid of it, things will obviously be much better.
Apologists have tried to fill in the gaps with a utopian vision [1] where we maintain the a similar standard of living but without wasting energy on conspicuous consumption. I agree that developing a culture that avoids conspicuous consumption would probably mean we could get by with less work. However there would still be enough work leftover to either require capitalism, or socialist style forced labor, both of which situationists explicitly reject.
